WASHING MACHINE.

Specification of Letters Patent. Pgtentefl Feb, 21 1922.

Application filed February 23, 1921. Serial No. 447,135.

invented a new and Improved Washing Machine, of which the following is a full, clear,

and exact description.

This invention relates to improvements in washing machines, an object of the invention being to provide a manually operable device of this character, in which a pair of dashers are. simultaneously reciprocated in' opposite directions. I

A further object is to provide a novel means for reciprocating the dashers and to provide a machine, which will be simple and practical in construction, strong, durable and efficient in use, and comparatively inexpensive to manufacture.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, to be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings:

Figure 1 is a view in side elevation of our improved washing machine;

Figure 2 is a top plan view thereof;

Figure 3 is a view in longitudinal section therethrough on the line 3-3 of Figure 2; and

Figure 4 is a view in transverse section on the line 1- 1 of Figure 3.

Referring in detail to the drawings, 1 represents a rectangular tank, which is supported on legs 2, and which has a cover 3 permanently secured thereto. The cover 3 is provided with a centrally disposed trap door et permitting the introduction of articles to be washed into the machine and the door 4 is locked in closed position by a pair of pivoted cleats, such as 5 mounted on the cover of the tank.

Mounted to reciprocate vertically within the tank are a pair of dashers 6 and 7 respectively. Links 8 and 9 are secured to the ends of the dashers 6 and 7 respectively and are movable vertically through openings 10 in the cover 3.

The upper dasher G is preferably solid throughout and is provided with a flap valve such as 11 adjacent each end to permit the passage of water upwardly through the dasher. The dasher 6 also includes a trap door 12 registering with the door 4 and secured in place by pivoted cleats 13.

The lower dasher 7 is preferably of some slatted or perforated material and includes a slatted trap door 14 registering with the doors 4 and 12 and secured in place'in the same manner.

The links 8 and 9 are guided in their vertical movement by collars or plates such as 15', carried by the top of the tank and angular wearing or chafing strips 16 secured in the inside corners of the tank guide the reciprocating movement of the dashers. The ends of the upper dasher 6 are recessed, as indicated at 17 to accommodate the links 9.

In operation the dashers 6 and 7 are reciprocated simultaneously in opposite directions, or in other words, the dasher 6 descends as the dasher 7 rises and vice versa. I have illustrated one convenient means for imparting this movement to the dashers, in which a pair of bearing brackets extend ing laterally from the ends of one side of the tank provide mounting for a crank shaft 18.

Adjacent each end the crank shaft is formed with oppositely disposed crank arms 19 and 20, respectively and at one end of the shaft, a =-.=.-ank handle such as 21, is provided for turning the same.

Adjacent each end of the other side of the tank, a link 22 is pivotally mounted on a bracket 23. Levers 24 each have one end connected to the links 22 and their other ends connected through the medium of links 25 to the crank arms 19. The intermediate portions of the 1evers 2 1 are pivotally connected to the upper ends of the links 8.

In like manner links 26 pivotally connected to the brackets 23 are connected to one end of levers 27. The other ends of the levers 27 are pivotally connected to links 28, which are in turn pivotally connected tothe crank arms 20. The intermediate portions of the levers are connected to the upper ends of the links 9.

It will be apparent from the foregoing description'that rotation of the crank shaft operates through the medium of the links 25 and 28 and the levers 24 and 27 to simultaneously reciprocate the dashers 6 and 7 The theory of operation is as follows: Clothes are introduced through the trap doors 1 and 12 onto the slatted dasher 7 it being assumed that the tank is already Water will passthrough the clothes and the dasher. Pressure on the under face of the dasher 6 is relieved by the flap valve 11. When the dashers are Withdrawn from each other, the Water will rush upwardly through the lower dasher 7, loosening the clothes from this dasher and preparing them for the next approach of the dasher 6.

'Although We have illustrated one of the "preferred embodiments of our invention, it

Will be apparent that various slight changes and alterations might be made in the general form and arrangement of the parts described Without departing from the invention and hence e .do not limit ourselves to the precise details set forth, but shall consider ourselves at libert to make such :slight changes'and alterations as fairly fall Within'the spirit and scope of the appended claims.

"'VV'e have described the machine as manually operated. It will be evident, however, that the shaft 20 might be coupled to a source of power in any appropriate manner to convert the machine into a power driven device. 1

l/Ve claim: V

1. In a Washing machine, a tank, a cover fixed to the tank, a pair of dashers in the tank, means for reciprocating the dashers simultaneously in. opposite directions, alined trap doors in said cover and dashers, and pivoted cleats normally retaining said doors in position.

2. In'a Washing machineya tank, a cover fixed to the tank, a pair of dashers in the tank, means for reciprocating the dashers simultaneously in opposite directions, alined trap doors in said cover and dashers, and pivoted cleats normally retaining said doors inposition, the uppermost of said dashers being of solid material and having a flap valve associated With each end-thereof, the lower dasher being slatted.
